From Funes, the memories:

These things he told me; neither then nor later have I ever placed them in doubt. In those days there were no cinemas or phonographs; nevertheless, it is odd and even incredible that no one ever performed an experiment with Funes. The truth is that we live out our lives putting off all that can be put off; perhaps we all know deep down that we are immortal and that sooner or later all men will do and know all things.
